Humming ear,..now in both after a cold?

can anyone help me please?

for about 2 years it was just a very low hum in RIGHT EAR and just random (but at nights when lying down trying to sleep) - i put up with it as wasnt too bad but now its got much worse (louder and every night) and there is also a ringing (like pressure build up when blood rushes to your head - that sort of noise you hear when you pass out) but that ringing is VERY low but possibly because the hum is overpowering it, I can hear the ring when I put my head under water in the bath, i noticed once when i took IBUPROFEN the humming went away??, so i took more but after few days it stopped working - anyway, I went to one Dr and he said "tinnitus , nothing can be done" , i went to another who said "its not tinnitus cos its in one ear" but was still at a loss and he referred me to ENT (which is 6 weeks time) - recently i got a cold, I never get colds and this one lasted over 10 days - during the outset of this cold the humming started to go over to left ear!! and louder!! - oh I was driven mad with it trying to sleep , anyway ive just been to ANOTHER Dr few days back, he had a look and said there was a little fluid on the left ear and that's probably from the 'cold' and so wont prescribe antibiotics ... he gave me 7 x 20mg Temazepam to help me sleep for a few nights - I took the tablets and guess what... the humming went away... before sleep and after sleep... I could lie there and move y head about, open my mouth etc and it would come and go like before - ive ran out of Temazepam and guess what? the humming is back... strange?

Along with that I also have sinus problem where i can hear my breathing in my ears if i breath through my nose - more in the right one (mostly affected one)

Iam also on Methadone which could possibly be cause but never had it for 4 of the 6 years ive been on it so probs not!

I now think it may be allergy, Iam taking a LOT of herbal supplements for my Liver Disease and I think it may be related and the ringing is like a 'pressure build up' sort of noise - the humming must also be part of it, so Im gunna stop all my supplements which include Milk Thistle, Multi-Vitamins, Cod-Liver Oil, Dandelion , Artichoke and Herbal Teas (although most of those have just started recently) if any I think it be Milk Thistle as thats the ONLY one ive been constantly taking, Milk Thistle is more likely the culprit if it were to be any of those...
